'Specification of Letters Patent.

Patented Nov. 22, 1910.'

To all it may concern.' 7.

Be it known that we, FRANK J Unrus and MALcoLn BLANC'H, citizens of the United -States of America, residing at Worcester, in' .the county of lVoi-cester and Commonwealth of Massachusetts, have invented a new anduseful Vacuum-Sweeper, oi; .which the fol' lowing is a specilicatwn. f1-

Ourinvention relates tofimprovements in pneumatic cleaners and consists in the peculiar construction, arrangement and combination of parts as more fully. hereinafter described.

An object of our invention is lto provide a pneumatic, sweeper in-.which the suctionl creating device is automaticallyI operated by the wheels of the sweeper being set in motion by the' stroke of thesweeper over any` surface by means of azhandle.

ln the drawlng, Figure 1 is a rear view of the invention 4with the cover removed. Fig. 2 is a viewI of' the front end of the same. Fig. 3 is a verticalwlongitudinal section of the saine. F ig. 4 is 'aview of; the nozzle head and a section of the dust receptacle.

Similar numbers refer to similar-parts throughout the several views.

Referring to the drawing, 1 is lthe casing having the apertures 2 protected by the screen 3. The removablel dust receptacle frame 4 having attached to it the dust receptacle 5 is adapted to. tit into the open end 6 of the casing 1 against the stri i '7 attached to the casing 1. The nozzle b is adapted to cover the end 6 of the casing 1 and be held in position or loosened by means of the thumb screws 9. The nozzle .head 8 has the duct 10 and the horizontal elongated inlet 11. The casing l has the roller 12 verticallyadjustable by means of the spring 16 and the thumb screw 13 operating the lever 14 on Irhe fulcrum 15. The bellows 17, 18 and 19 'attached to the casing areof the common kind and require no particular description. The bellows 17, 18 and 19 respectively have the levers 20 attached thereto by means of the screws 21. The casing 1 has the projections 22 having the bearings 23 for the crank shaft 2li. To the crank shaft 21 are attached the sustainingwheels 25 and 26 having the corrugated periphery 27 and the pins 28 forming a bearing for the lower ends of the connecting rods 29, the other ends of which are movably conoum, c

nppucation'mes ,my 21, 1910. lseran No. 573,125. nected with the outer-ends of levers 20 at tached to the bellows 17 and 19 res actively. Y ...The connecting rod 301 connects t e crank- 'Shaft 24 andthe lever 20 vattached to the-bel- 'lows 18. The handle 31- has the 'pivotal' connection 32 with the casing 34- is the surface over .which tle'cleaer is operated. In operating this device the parts being 1n the` position: shown in Figs. 1,2 and' 3, the operator bymoving the device by means of thel handle 31' over the surface 34, havmg adjusted thej roller `12fby the thumb screw 13 'so that the nozzle inlet 11 is at the desired height from the surface-34, the sustaining wheels 25vand 26 being set in motion by the friction of their corrugated periphery against the said surface 34, operl.ate the said bellows. 17,18 and 1.9 in rotasuch material as to retain the particles of dust and larger objects and allowing the air to pass through the walls thereof through the apertures 2 into the said bellows 17, 18 and 19, respectively, the screen 3 guarding the said receptacle from Abeing drawn into the said apertures 2.

Having thus described our invention what we claim is:

1. Ina vacuum cleaner, a casi'n having apertures, a nozzle head having an e onga'ted inlet detachably connected with said casing, a dust rece tacle in said casing detachably connected therewith, said nozzle head being provided /with V,pan o ening therethrough from the said inlet an communicating with the dust receptacle, a screen vguarding said apertures, a plurality of suction creating devices connected with the said casing above said apertures, an adjustable roller connected with said'casing and ada ted for vert-ical adjustmentof one end t ereof, a crank shaft movablyconnected with the said andadapted to operate said suction creating .10 casing, sustaining corrugated wheels att-ached. 'to the said crank shaft and connected with.

devices in rotationyby the rotary motion. of `said wheels, a handle -pivotally connected with-.the said casing, and a cover, all sub- 1 j stantially as shown.

2, In a pneumatic sweeper the combinationof a casingA having apertures, a screen guarding said apertures, lsustaining whe-'els :onneet'edjfvvvithlsaid casing, a dust collector in said -cas' ldetachably connected there- Vyvith, a nozz eheadlgdetchably `connected 'withsaid'casin and having an air passa e ther e'th`rough, l rom said. du'st" receptace widening,'into an elongated-horizontal inlet therem,.-mean sg; f,or the vertical adjustment of said casing, means :for creating a continuous suction in said air passage through said-dust receptacle connected 4with and open. at'its' front end andjhaving/aper vtarea,2a;screen guarding said apertures, a

- In' testimony whereof we have signed our'.

names to this specilication 'in the presence'o'f two subscribing witnesses.
